Good sowing days

13 days

The moon passes through all twelve signs of the zodiac each month, and biodynamic growers match what they sow to the element the moon is travelling through. In December 2026 the moon is ascending — the traditional time for sowing and grafting — on 14 days. The strongest sowing dates fall on the 10, 11, 12 and 10 other days. Days marked in the table below sit near a lunar node or perigee, when traditional practice is to leave the soil alone.

What to sow in December

Nothing in the plant database is sown in December — a month for planning, composting and tool maintenance rather than sowing.
